FRI a Method of Reading Cardiotocography (CTG) in Labor

The objective of the study is to investigate the FRI's ability to identify cases requiring urgent intervention which will present an adverse perinatal outcome (respiratory acidosis, metabolic acidosis, Apgar index, etc.) compared to the classical interpretation of CTG. Patients whose CTG in labor will be considered non-reassuring will be enrolled and randomized into two groups. The "Fetal Reserve Index" algorithm will be applied to the first group of patients. The second group of patients will, however, be managed according to the usual protocols internal management.
